Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a key cassette storage mechanism, and more particularly to a key cassette storage mechanism that is used for centrally managing keys by arranging a plurality of storage mechanisms to form a key station.

0002

[Background Art] Recently, with the development of construction technology and the concentration of population in cities, the number of buildings has increased as the number of buildings has increased.
Unmanned management systems have been introduced to computerize the management of commercial buildings and residential condominiums to reduce labor costs and improve reliability. For example, in addition to managing the entry and exit status of condominium tenants and residents at the entrance and exit, operating alarm devices and controlling lighting and air conditioning in common areas, we also prevent suspicious persons from entering and exiting the condominium, thereby increasing safety. is ensured.

[0003] In addition, by preventing the keys for opening and closing each room in an apartment to be centrally controlled by a computer in a key box at a predetermined location, it is possible to accurately grasp the entry and exit status of tenants and residents. The keys are inserted and withdrawn using individual cards (see "Key Box" in Japanese Utility Model Application Publication No. 59-562921).

[0004] Furthermore, the applicant of the present invention centrally stores keys, accurately grasps the entry and exit status of apartment tenants and residents at the entrance and exit, and operates alarm equipment, lighting and air conditioning of common areas, etc. The company has already filed a patent application for computer-controlled computer management to prevent suspicious people from entering and exiting apartments (see Japanese Patent Laid-Open No. 2-266074, ``Key Centralized Management Control System'').

[0005]

By the way, in the conventional key cassette storage mechanism, each tenant has a box body with a bottom, and keys are stored in the box body.

[0006] For this reason, the box main body is formed large, and a key station with a plurality of box main bodies arranged becomes large, making it difficult to save space and making it difficult to select the installation location of the key station in a high-rise building. This has the disadvantage of being disadvantageous in practical terms.

[0007] Furthermore, as disclosed in Japanese Patent Application Laid-open No. 2-266074, in a device in which a key is stored in a case part and inserted into a predetermined part of a key storage board, the case part consists of an upper case and a lower case. When the key is stored between the upper and lower cases, the upper and lower cases and the key are connected by a chain.

[0008] For this reason, the entire key is exposed from the case part, making it easy to make copies of the key and reducing the reliability of centralized management.

Furthermore, when a key is transported, it is generally attached to a key holder. However, because the key holder and the key are engaged so that they are perpendicular to each other, the appearance of the key holder that stores the key inside the key holder made of a flexible material is deformed, making it difficult to transport and making it difficult to use. There is an inconvenience. Further, in a key holder that exposes the keys, the shapes of the keys and the key holder are exposed as they are, which further impairs usability.

0010

[Means for Solving the Problems] Therefore, in order to eliminate the above-mentioned disadvantages, the present invention provides a key cassette having a longitudinally extending key storage groove and a fixing locking part, which functions as a surface member. A plate-like member, a hole for inserting and removing the key cassette formed in the plate-like member to match the cross-sectional shape of the key cassette, and a cover that opens and closes on the rear side of the plate-like member to close the hole, and a plate-like member. A storage frame portion that is connected to the rear surface of the member and stores the key cassette, and an engaging pin that protrudes into the storage frame portion and engages with a locking portion of the key cassette when the key cassette is inserted from the hole portion, and is engaged via a link mechanism. The present invention is characterized by comprising a storage mechanism including a solenoid that pulls in the dowel pin and releases the engagement.

[0011]

[Operation] With the invention as described above, the key is stored in the key cassette, the key cassette is inserted into the storage frame of the storage mechanism, the engaging pin is engaged with the locking part of the key cassette, and the storage mechanism A key cassette is stored inside, reducing the key storage space.
